plastic zippers (mainly made of PE/PP) are widely used across seven major sectors, valued for re-sealability, moisture & oxygen resistance, and easy access.

1. Snack Foods (Largest application, ~35% market share)

Covers nuts, daily nut mixes, puffed snacks, dried meat, candies, chocolates, preserved fruits and sweetmeats.Requirements: Excellent moisture and oxygen resistance to keep food crisp and flavorful. Slider zippers paired with tear notches are commonly used; stand-up gusseted bags with zippers have become the standard packaging for nuts.

2. Frozen Food & Meat Products (High-growth sector, ~20% market share)

Includes frozen meat, seafood, dumplings, glutinous rice balls and chilled poultry.Requirements: Resistance to low temperatures (-18℃ to -40℃) and cracking, superior sealing to prevent odor transfer. Double zippers are widely adopted.

3. Ready Meals & Instant Prepared Food (Fastest-growing, 15%+ annual growth)

Covers ambient/low-temperature ready meals, pre-cooked dishes, braised food and instant porridge/rice.Requirements: Heat resistance for cooking and microwave use (over 100℃), oil resistance and tight sealing for freshness preservation. Monomaterial PP zippers are mainstream for easy recycling.

4. Dry Goods, Beverage Powders & Grain Products (Stable demand, ~15% market share)

Includes tea, coffee beans/powder, meal replacement powder, grains, flour and dried wolfberries/jujubes.Requirements: Strong barrier against moisture and oxygen to avoid caking. Re-sealable slider zippers suit frequent opening and long-term storage.

5. Pet Food (~8% market share)

Covers dog/cat food, pet freeze-dried treats and animal feed.Requirements: High load-bearing capacity, effective sealing against moisture and pests, and resistance to grease leakage. Slider zippers are essential for large packages over 2kg.

6. Baked Goods & Instant Pastries (Upscaling trend)

Includes bread, cookies, mooncakes and cakes.Requirements: Moisture retention and mild oxygen resistance. Zippers combined with air valves help extend shelf life and maintain taste.

7. Household & Catering Fresh-Keeping

Household use: Food sorting, refrigerator storage, leftover sealing, fruit & vegetable preservation and portable food packaging.

Catering use: Central kitchen ingredient storage, takeaway leakage prevention and cold chain logistics.Requirements: Food safety compliance, reusability, low temperature and microwave resistance. Translucent PE zipper bags dominate this segment.
